You can find this in Prapor's assort. There's no thumbnail for this item and it's normal. Attach it to the left side rail of your firearm to see it in action.

The bottom-right is a secondary crosshair for close-range use.

A dependency mod for AT's weapon mod. All credits goes to him. I just have the permission for translating his work and upload it here. Language barrier exists so keep in mind that there will probably be limited support for this mod.

Only in-game texts are translated. Others such as server log is still Chinese but it doesn't affect the gameplay.

Version 3.4 is only compatible with Aki 3.4.0 or 3.4.1.

Version 1.0 is backward-compatible with Aki 3.3.0 to as old to Aki 3.1.0.

Installation Guide:

Put the "AT-腰射准星" folder into "<ur Aki path>\user\mods" folder. Typical server mod procedure.
